Simplified effective stress modeling of shear wave propagation in saturated granular soils

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

This paper improves a simplified soil hysteresis model for one-dimensional fully coupled effective stress analysis of site seismic response that addre......

Exploration of Ground Vibration due to Trains Moving on the Nearly Saturated Ground

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

A study of the effects of degree of saturation on the nearly saturated ground dynamic response caused by high-speed trains moving is presented. The so......

Determining Bishop's parameter chi based on pore size distribution

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

Extension of the effective stress concept to unsaturated soils has been a major concern for decades. Recent studies significantly contributed to the u......

Effects of particle breakage on the compression behaviour of gap-graded carbonate sand-silt mixtures

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

Isotropic compression tests were conducted on a series of gap-graded mixtures of a carbonate sand (CS) from the South China Sea and a fine crushed qua......

Splitting tensile mechanical behavior and failure characteristics of thermally-damaged rock

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

The Brazilian disc specimen (BDS) and flattened Brazilian disc specimen (FBDS) test was conducted on the thermally damaged rock (from room temperature......

Simulation on heterogeneous rocks with a flaw using grain-based discrete-element method

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

To take into consideration the effect of mineral microstructure on crack growth and mechanical properties of heterogeneous rocks containing a single p......

A novel method to obtain the dynamic tensile stress-strain curve of rocks

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (1)

The dynamic tensile stress-strain behaviour is desirable in evaluating the stability of geo-structures subjected to dynamic loading. However, the dyna......

Mechanical behaviors of artificial samples containing multiple parallel joints during shearing under constant normal stiffness conditions

期刊: GEOTECHNIQUE LETTERS, 2021; 11 (2)

The present study experimentally investigated the influence of number of joints on the evolutions of mechanical behaviors of multi-joint samples durin......

Scaling effects on the centrifuge modelling of energy piles in saturated sand

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (1)

Although various researchers have reported that scaling effects should be considered carefully when modelling the mechanical behaviour of pile in sand......

Drained response of rigid piles in sand under an inclined tensile load

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (1)

The response of rigid piles in sand to an inclined tensile load is poorly documented and understood, particularly when the load is cyclic. This is bec......

Effect of strain rate on macro- and micro-failure characteristics of marble from SHPB tests

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (1)

A rock's microstructural characteristics reflect its macroscopic mechanical properties. Here, the effect of impact load on the microstructural charact......

Drained cylindrical cavity expansion analysis in anisotropic soils considering 3D strength

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (2)

Anisotropic behaviour and three-dimensional (3D) strength are two significant properties of soils. This paper incorporates the spatially mobilised pla......

Swelling behaviour and microstructure of biochar bentonite

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (2)

Biochar bentonite is a potential candidate as a porous layer for nuclear waste repositories. It would provide an ideal niche for bacteria that could f......

Effect of the ordering of cyclic loading on the response of suction caissons in sand

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (2)

Wind and wave action on offshore wind turbines causes irregular cyclic loading on the foundation that can lead to rotation accumulation of the structu......

Liquefaction resistance of sand amended with biochar

期刊: GEOTECHNIQUE LETTERS, 2020; 10 (2)

Biochar is a solid carbon material produced by heating organic biomass in the absence of oxygen through a process known as pyrolysis. Scientists and p......
